The lights that are blinking are indicating an error code--the particular code you describe is a "heater error". You will have to check the circuit for an open heater element, loose or broken wire, defective main control board. The part number for the main board is DE92-02256C. Hope I helped you!

It need new dispenser and need to be replace with new one

I wish you had received an answer. Mine is doing the same.

That is usually indicating a leakage error, which means water has leaked down into the base of the dishwasher. You'll have to pull the dishwasher out, pull off the side panels, and dry up all the water, but you still have the problem of figuring out where the leak came from and fixing the problem before you can use the dishwasher. The most common source of leakage in a Samsung DW is the drain pump and/or drain hose.

Had a look in the user manual for your dishwasher.http://downloadcenter.samsung.com/content/UM/201211/20121101114232459/DW7933LRASR-00141A-02.pdf

Page 26 shows blinking Heavy light means there is leakage in the dishwasher. Most likely there is water in the base under the drain sump which could cause the flood switch to trip. Turn mains power to dishwasher off. Pull it out from under kitchen bench without breaking the hoses. Put some towels on the floor and turn dishwasher back and forth on incline to get water out. Wait a little and turn on. If no difference then you need to dry the base and find the source of the leak. More likely the door seal.
